When many cells undergo necrosis at once, then definable patterns of
necrosis are produced, depending upon the nature of the injury, the type of
tissue, and the length of time. This is an example of coagulative necrosis.
This is the typical pattern with ischemia and infarction (loss of blood
supply and resultant tissue anoxia). Here, there is a wedge-shaped pale
area of coagulative necrosis (infarction) in the cortex of the
kidney.
